Creating Terrain in Rhino From Contours
To begin this tutorial, you should already have AutoCAD contours

In Rhino, select File → Open.
Locate your AutoCAD file and click OK.

Your contour lines should
show up. Depending on whether your
AutoCAD lines were assigned elevation values, you may see that contour lines
are at their proper elevations. If they
do not have elevation values, you can go back and assign these values in
AutoCAD and reopen it in Rhino.

Type PackageManager and hit
Enter.
Type terrainmesh in the
search bar and wait until it shows the result.
Select the TerrainMesh
plugin and click OK.
5. Type TerrainMesh and hit
Enter.

When prompted to “Select
Objects”, select the contours you wish to use.
They will turn yellow when selected. Hit Enter.
(to select all the contours on one layer, use the command SelLayer and shoose the layer you want to use.
)
7.
You will be prompted to
select a tolerance in meters. Typically
the default tolerance of 1 is good.
Click OK.

Your progress will display
as a percentage complete. Wait for it to
finish. This may take several minutes.

When the process is
complete, your new mesh will appear as a triangulated surface in Shaded view
